I need the entire main board replaced/rebuilt/refurbished for my TV (it's the whole board that sits on the floor of the inside cabinet). Repairman is quoting me about $815. Would like to know if that's a fair price, and also if there is somewhere I can buy one of these myself and put it in maybe for less. What part number am i looking for? Thanks!

First thing you should do is to invest in a really good surge protector for your TV. Then when you replace the capacitor again use a good capacitor. Cheaper is not always better. Rubycon seems to do the best for me. There may be other suggestions, however I have the best luck with them.
